So last night I took a trip to the local drag track and was able to do 2 passes.
Ok my first run I got a 12.5 and on pass 2 I pulled a 12.3 (new personal best).
24PSI on 98 Oct.

Are these times normal for the mods I have?
I have attached a log from my 12.3 run, please take a look at tell me what you think as I am always looking for good input on tuning.

Thx

 

Looks good... 98 octane might allow for more timing.

12.3 is a great time though, good driving

 

right but isnt he running more lean than you would typically on say 93?

i am still trying to figure out the balance between advancing timing and leaning out AFR for best power, most stable combusion. any thoughts?

 

I dont think so. Depending on EGTs he should be able to go a tad leaner.

 

I run at 11.5 on 93 octane...I think he should bump up the timing 1* per run until he sees knock.

 

What was your trap speed? That tells alot more about WHP than ET does which can vary a little depending on the driver.

 

Same setup a little richer (.4) and a tad more timing I was able to get a 12.1 this time out.

Why does ignition start at 11* at 6300 rpm and stay at 11* to 7800 rpm? Do you have late intake valve timing near redline?
